摘　　要：为探究湖滨带藻类水华期水体异味物质的空间分布规律,2019年6—10月对巢湖湖滨带水体理化参数和异味物质进行月度调查,分析湖滨带水体异味物质的空间分布特征,并探讨影响其空间分布差异的主要因素。结果表明:巢湖湖滨带藻类水华期水体异味物质浓度在空间上总体表现为西北部湖区最高,南部湖区次之,东北部湖区和北部湖区最低的分布特征,藻类生物量高低及其分解是水体异味物质产生空间分布差异的主要原因。风向和风速间接影响了湖滨带水体异味物质的空间分布,其中北部湖区受风速和风向的影响最为明显,其次是南部湖区和东北部湖区,西北部湖区影响最小。此外,湖滨带植被通过影响该区域藻类水华堆积及消散过程加剧了水体中异味物质的富集。The physicochemical parameters and odorous compounds concentrations in the water column of the littoral zones of Chaohu Lake were detected monthly from June to October 2019 to explore the spatial distributions of odorous compounds and the main factors affecting them.The results showed that the concentrations of odorous compounds in the littoral zones decreased in the sequence of the northwestern lake region>the southern lake region>the northeastern and the northern lake regions mainly due to the algal biomasses and its degradation.Wind direction and wind speed also played important roles in affecting the northern lake region most,then the northeastern lake regions and the northwestern lake region least.In addition,vegetation in the littoral zones intensified the enrichment of odorous compounds by affecting the accumulation and dissipation of algal blooms.
